Discovering the Depths: Scientists Uncover 19,000 Undersea Volcanoes

Scientists use satellite data to discover 19,000 undersea volcanoes, providing new insights into the Earth’s geological makeup.

A team of scientists has discovered over 19,000 ancient volcanoes, known as seamounts, at the bottom of the ocean using satellite data. These seamounts are formed by volcanic activity on the ocean floor and can range in height from 3 to 10 kilometers.

Hidden World of seamounts

Only 20% of the ocean floor has been mapped by ships, which means there may be thousands more seamounts yet to be discovered. Seamounts can help scientists better understand the tectonic plates and the Earth’s mantle, as well as impact deep ocean currents and serve as habitats for various marine life.

The discovery of these seamounts provides a unique opportunity for scientists to learn more about what lies beneath the ocean’s surface.

Bioluminescent Waves in San Diego: A Captivating Coastal Phenomenon

“Experience the enchanting glow of bioluminescent waves along San Diego’s coast, a mesmerizing natural phenomenon caused by phytoplankton.”



Bioluminescent waves have become a captivating spectacle along the coast of San Diego County, attracting scores of SoCal residents eager to witness this natural phenomenon firsthand. The mesmerizing glow is caused by tiny light-producing organisms called dinoflagellates, which reside in the ocean. When these phytoplankton are agitated by waves or splashing, they emit a beautiful luminous display.

Recently, the bioluminescent waves have been observed in various locations including Point Loma, Sunset Cliffs, Blacks Beach, La Jolla Shores, Encinitas, Carlsbad Beach, Tamarack Beach, and Oceanside. The unpredictability of these blooms adds to the excitement, as one never knows when or where they will occur.

For San Diego residents hoping to experience the magic of bioluminescent waves, a few tips can enhance their chances. First, checking with local aquariums and maritime institutes such as the Birch Aquarium, the Aquarium of the Pacific, and the Ocean Institute can provide updates on bioluminescence sightings. These institutions often share information on their websites or social media platforms.

Finding a dark location away from artificial light is crucial for optimal viewing. Experts recommend heading to the shore before the moon rises, approximately two hours after sunset. This way, the darkness amplifies the glow, and the waves become even more enchanting.

Tracking hotspots is another useful strategy. The best locations for witnessing bioluminescent displays can vary from night to night. By monitoring social media platforms and hashtags associated with bioluminescence, residents can stay informed about the latest hotspots and plan their visits accordingly.

The return of bioluminescent waves to the San Diego coastline has sparked a sense of wonder and awe among locals. It’s a reminder of nature’s remarkable beauty and the extraordinary phenomena that unfold right in our own backyard. So, grab your camera, head to the coast, and immerse yourself in the captivating glow of bioluminescent waves.

Kia partner, The Ocean Cleanup, delivers record 55-ton ocean plastic haul 



  • Kia global partner, The Ocean Cleanup, sets a new record for the amount of plastic reclaimed from the world’s oceans
  • 55 tons of ocean plastic delivered to Victoria, Vancouver Island, Canada
  • Plastics will be recycled; proportion to be used in future Kia models under multi-year partnership
  • Catch delivered to shore from 1.6-million-square kilometer Great Pacific Garbage Patch (GPGP) by The Ocean Cleanup’s System 002
  • The Ocean Cleanup announces scale-up to largest-ever System 03 in ongoing mission to remove 90% of floating ocean plastic by 2040
  • Initiative aligns with Kia’s mission to become a sustainable mobility solutions provider
  • Kia remains committed to more than 20% increase in plastic reuse by 2030 and achievement of carbon neutrality by 2045
  • View film of record ocean plastic reclamation here 

SEOUL, South Korea /PRNewswire/ — Kia plans to use recycled plastic from a 55-ton haul recently reclaimed from the Pacific Ocean in its new EV models. The record-breaking amount of plastic reclaimed by Kia’s global partner, The Ocean Cleanup, marks the next phase in a seven-year global partnership agreed in April 2022 as part of Kia’s transformation into a leading sustainable mobility solutions provider.

The Ocean Cleanup, the international non-profit project with the mission of ridding the oceans of plastic, landed its plastic catch at Victoria, Vancouver Island, Canada. The record catch was removed from the Pacific Ocean using The Ocean Cleanup’s System 002 extraction technology following a voyage through the Great Pacific Garbage Patch (GPGP).

Recycling of the plastic will begin shortly, and Kia will use a proportion of the material in future models. This policy aligns with Kia’s commitment to provide sustainable mobility solutions that have a measurable impact on achieving sustainability at scale.

Charles Ryu, Senior Vice President and Head of the Global Brand & CX Division at Kia Corp., commented: “The record catch of plastic brought to shore by The Ocean Cleanup is tangible proof of how technology can deliver sustainable solutions at scale. Initiatives such as this one perfectly align with Kia’s transition to a sustainable mobility solutions provider and our Plan S strategy, through which we embrace the needs of our customers and the protection of our environment by acting as a responsible corporate citizen.”

Overcoming Barriers to Fire Ant Allergy Treatment

Addressing barriers to fire ant allergy treatment: A case study highlighting solutions for improved access and outcomes.



A recent case study published in the Journal of Allergy and Clinical Immunology: In Practice sheds light on the obstacles faced by families seeking venom immunotherapy for fire ant allergies. The study focuses on a 4-year-old boy from New Orleans, Louisiana, who suffered a severe allergic reaction after being stung by fire ants. Dr. John Carlson, a pediatric allergy and immunology specialist at Ochsner Health, led the research.

Red Fire Ant
« Case Study: Overcoming Barriers to Venom Immunotherapy for Fire Ant Allergy Patients

The Prevalence of Fire Ants:
The study reveals that fire ants, particularly the black and red imported species, have become widespread in the southeastern United States. In fact, a staggering 58% of New Orleans residents reported being stung by fire ants in the past year. Despite efforts to avoid these stings, individuals with a history of anaphylaxis still face the risk of being stung.

Barriers to Treatment:
While venom immunotherapy has been proven safe and effective, accessing adequate treatment remains a challenge. The study suggests that forming broader coalitions involving community partners, patient advocacy groups, physicians, and lawmakers is essential to addressing the overlapping hazards faced by families living in poverty.

Collaborative Solutions:
Dr. Carlson emphasizes the need for exploring all available resources to assist families with transportation barriers, lack of childcare, and difficulty taking time off from work. To create sustainable change in underserved communities, it is crucial for all stakeholders to work together. Parents of children with fire ant allergies must have access to life-saving immunotherapy treatments.

Investing in Marginalized Communities:
Investing in marginalized communities is particularly important to mitigate the effects of exposures on child health. The study underscores the importance of engaging in dialogue with families, schools, clinics, and other stakeholders to identify the best strategies for improving access to care and achieving more equitable outcomes.

Call to Action:
This case study serves as a call to action, raising awareness of the barriers faced by fire ant allergy patients and their families. By fostering collaboration among healthcare professionals, community partners, and policymakers, meaningful change can be achieved, leading to improved access to vital treatments for those in need. Together, we can overcome barriers and ensure better outcomes for fire ant allergy patients.
